Single-shot hard X-ray spectrometer with uniform spatial and spectral response. [PDF]

J Synchrotron Radiat
We demonstrate a single‐shot hard X‐ray spectrometer based on small‐angle scattering from glassy carbon that is insensitive to X‐ray free‐electron laser beam‐dependent spatial and spectral variations. Comparison with established X‐ray Thomson scattering diagnostics using stochastic correlation X‐ray spectroscopy demonstrates full‐bandwidth coverage ...

A BIST circuit for random jitter measurement [PDF]

, 2012
textJitter is a dominant factor contributing to a high bit error rate (BER) in high speed I/O circuitry, and it aggravates the quality of a clock signal from a phase-locked loop (PLL), subsequently impacting a given timing budget.

Feasibility study for high bit rate pulse position modulation in fibre communications [PDF]

, 2013
With the rapid progress of optical communication systems, capacity limitation becomes important in high bit rate links. Overcoming this limitation may involve using different modulation and multiplexing methods, including RZ modulation with on-off keying

Random walk with barycentric self-interaction [PDF]

, 2010
We study the asymptotic behaviour of a $d$-dimensional self-interacting random walk $X_n$ ($n = 1,2,...$) which is repelled or attracted by the centre of mass $G_n = n^{-1} \sum_{i=1}^n X_i$ of its previous trajectory. The walk's trajectory $(X_1,...,X_n)

Statistical analysis of first-order bang-bang phase-locked loops using sign-dependent random-walk theory [PDF]

, 2010
Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear due to the hard nonlinearity introduced by the binary phase detector (BPD). This paper provides an exact statistical analysis of the steady-state timing jitter in a first order BBPLL when ...

Binary phase detector gain in bang-bang phase-locked loops with DCO jitter [PDF]

, 2010
Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the BPD and applying linear ...

Output-jitter performance of second-order digital bang-bang phase-locked loops with nonaccumulative reference clock jitter [PDF]

, 2011
Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear systems due to the binary phase detector (BPD). While they are typically used for clock and data recovery, the ongoing trend toward digital loop implementations has resulted in several ...
